Lift the console cover. Some models, like Komatsu, need a wrench to remove two 10mm bolts.
Hold the cover out of the way so you have space to work. Put bolts and washers somewhere safe.
Move the cover gently to loosen it. You might not need to take out every bolt.
Take off the throttle dial and put it aside.
Push the joystick boot through the hole in the cover and set the cover aside.
If the key switch will not come out, do not force it. If needed, start taking off the side covers.
Tip: Be gentle with all wiring and connectors. Pulling or bending wires can break the excavator display panel or the display panel controller.
Locate Monitor Display Excavator
Most excavators have the monitor display excavator inside the operator’s cab. You will see the excavator display panel in the middle, close to the main controls. For example, the DX50Z-7 Mini Excavator has a color LCD monitor in the cab. This spot lets you see machine data and controls easily.
Caterpillar and other big brands also put the display panel controller in the center of the cab. You can get to it by taking off the console covers and side panels. The display panel controller is usually near buttons for menus, backup cameras, and other features. Some cabs have consoles that tilt up or touchscreen monitors for easier access.
When you find the excavator display panel, look for extra covers or brackets. Take them off carefully. Always keep screws and small parts safe. This helps you not lose anything while you replace the monitor display excavator.
Step-by-Step Replacement Process
Disconnect Battery
Begin by disconnecting the battery. This keeps you safe from shocks. It also protects the monitor display excavator from damage. Always take off the negative cable first. Then remove the positive cable. Use tools with insulation. Keep metal things away from the battery.
Alert: Do not skip this step. If you short the battery, it can start a fire or cause burns. You could get badly hurt. Disconnecting the battery also keeps the wiring harness safe from shorts.
Remove Old Display
Now, take out the old display. First, loosen the screws or bolts holding it. Pull the display forward gently. This lets you reach the wiring harness. Carefully unplug all connectors. Do not pull or twist the wires. If you see dirt or rust, clean the connectors with a dry cloth.
Many people have problems at this step. The table below lists common issues and fixes:
